PlayStation 4 dev idc released new scripts on Github that invoke the PS4 kernel to decrypt the contents of a PS4 update file (firmware) and pup unpacker scripts, now before you ask no this release is not going to get you any steps closer to a PS4 CFW but as zecoxao outlines on his twitter this can help "porting webkit exploit everywhere, for instance. you can decrypt any usermode elfs from 1.00 to 3.55/3.70 because sony forgot to change keyset",
PuP Decryptionpup_decrypt: A utility to invoke the PS4 kernel to decrypt the contents of an update file. The default (hardcoded) operation is to decrypt /mnt/usb0/PS4UPDATE.PUP. This will output a number of files (depending if a normal or a recovery update):
These decrypted updates can then be further unpacked using a tool capable of doing so.
Note The PS4 will refuse to decrypt updates in some cases: Versions older than the installed version (for the most part, there's exceptions for things like beta versions).
Versions for a different product code (retail cannot decrypt test or debug updates)

pup_unpack A utility to unpack PS4 update blobs that have been previously decrypted using pup_decrypt.
Note This utility will not unpack the contents of nested filesystems. The filesystem images in updates are FAT32, exFAT, etc images and can be mounted or unpacked with other tools.

- Q (via twitter): What could this lead to ?
- A (via zecoxao): porting webkit exploit everywhere, for instance . you can decrypt any usermode elfs from 1.00 to 3.55/3.70 because sony forgot to change keyset
- Q (via Twitter): Is the first step to actual CFW, is there a way to repack and encrypt the PUP again?
- A (via zecoxao): no and there never will be unless you own a 15 million dollar quantum computer

(Original Article from Nov. 14) Is the PS3 a bit closer to gaining Hardware Acceleration (via RSX) in OtherOS (Linux) with a proper driver to enable the GPU chip? We are not there, but we may be getting closer to a reality. Earlier this year (back in April) we detailed some of the progress that the busy dev RenéRebe has made with unlocking the potential of the PlayStation 3's RSX chip and now today we have been greeted with a new video and what we can expect with this project as the developer starts to undertake the challenge of further unlocking one more component of the Ps3 hardware,. The developer has alot of videos on other intresting subjects in his diverse YouTube channel >>> (Bits and More) <<< many very informative video's..Continue reading
4.84 Dualboot Firmware (Choose a release from littlebalup or Overflow)We have two version of 4.84 Dualboot firmware that was released for CFW user's. One by developer @littlebalup and also one by developer @Bobby_Downgrades (Overflow) (bobby did make a mistake on his previous Overflow dualboot version but is an experienced developer and took full credit for the mistake while trying to making it right for user's that had issues.) .Now for those of you who do not know about a DB firmware, A dualboot firmware is an official firmware with one key difference and that being it has the ability to install a CFW over it. An idea originally brought to the scene by @habib
So here is the scenario you on CFW already (this is only for CFW user's only) and you have your Gran Turismo 5 (or any disc game) like pictured and you want to play/connect to PSN. However you do not want to be banned and want to reduce your chance of a ban . The good news is you can by simply installing a dualboot firmware for the latest firmware, in this case in one of these 4.84 release and when your done gaming online with your disc based game and you want to play Super Mario Bros. or the Legend of Zelda on your PS3 through RetroArch simply re-install the 4.84 CFW of your choice and be back in CFW land of features, This has been a very effective way to avoid bans on games like first person shooter that are much more proactive in detecting modded consoles (as they should be) ..Continue reading
